The purpose of the 9000A-xxxx series Fluke Interface Pod, hereafter referred to as the pod, is to interface any 9000 Series Micro system Troubleshooter to a piece of equipment employing a specific microprocessor.
The 9000 Series Micro system troubleshooters are designed to service printed circuit boards, instruments and systems employing bus-oriented microprocessors. While the architecture of the troubleshooters mainframe is general in nature and is designed to accommodate processors with up to 32 address lines and 32 data lines, the interface pod adapts the general purpose architectures of the 9000 series to a specific microprocessor, or microprocessor family. The interface pod adapts the 9000 series to microprocessor specific functions such as pin layout, status/control functions, interrupt handling, timing, size of memory space, and size of I/O space.
The pod consists of a pair of printed circuit board assemblies mounted within a small break resistant case. A shielded 24 conductor cable connects the printed circuit boards to the troubleshooter; a ribbon cable and connector provide connection to the unit under test, hereafter referred to as the UUT.
There are more than 50 microprocessor-specific Interface Pods for use with the 9000-series or 9100-series mainframe. The pod functions as the test interface between a suspect circuit board's microprocessor circuitry and the mainframe. Each Interface Pod has a self-contained system with its own microprocessor, RAM, ROM, and I/O memory space. The pod can run board-resident programs such as initialization and diagnostics. The Interface Pod uses the board's clock circuit ensuring that all tests are performed at the board's designed speed. Automatic bus line monitoring eliminates the need for probing and enables detection of both static and dynamic faults. The pod has input protection circuitry against over-voltage and incorrect pod insertion. A self-test socket is provided for quick confidence checks.
